As presented by a server machine or a device, a graphical user interface may include first and second panels presented on a display. The first panel may show a set of menu items that include a menu item that is highlighted by a shape that surrounds the menu item. The second panel may be presented adjacent to the first panel and may show a set of one or more sub-menu items that correspond to the highlighted menu item. In response to a selection of the highlighted menu item, the presenting of the graphical user interface may include presenting an animated transition that shows the first panel folding out of view underneath the second panel, the third panel unfolding into view from beneath the second panel, and the shape transitioning from surrounding the menu item in the first panel to surrounding a sub-menu item in the second panel. |
